Many stores have reopened over the past few weeks at Westfield Montgomery mall — and more are still in the process — but the list of permanent closings keeps getting longer. GNC is the latest to exit, following the departures of the Microsoft Store, Everything But Water, Hanna Andersson, Steve Madden, David’s Tea, Bose and the Beefsteak restaurant. At the Dining Terrace, where many of the smaller eateries are back but the larger ones are still dark, Indian restaurant Mirch Masala is being replaced by a hot dog stand. As for new tenants, the next big openings will be the Lego store and Moorenko’s ice cream.
